Any applied products that have the potential to communicate their emissions to the indoor air would need to be considered for IEQc4.1, but if they have little or no potential they can be excluded. This leaves room for interpretation, so projects are encouraged to take an inclusive view of what they include. For more detail, reference LEED Interpretations 809, 811, 3716, and 5955. These are not explicitly applicable to all LEED projects and credits, but nonetheless offer the most specific guidance LEEDuser has found on this issue.
